As a person who has been eating pancakes for 20 years, I feel it's my responsibility to answer this question. In addition, I would like to say that I have eaten pancakes near the school. I want to cry. It's so bad that I want to sell them. Even what I do is better than you?
Let's get to the main point. The crust of the vegetable pancakes you said is actually pancakes. Please pay attention to whether the pancakes are fried or not? Pancakes are made by burning, and the tools used are pancakes (pancakes made of pancakes are smaller than those made of ordinary Shandong pancakes, with a diameter of about 50 cm) and bamboo billets (I don't know how to explain this, we say bamboo billets, which are sword tools made of bamboo). The raw materials are batters made of wheat, but now we use more flour, that is, flour mixed with water The batter is stirred and then placed on the hot pan with a spoon. The whole pan is slowly spread out with bamboo billets. It's a spiral spread from the outside to the inside. It's not just a random spread. It's a technical job. Almost no one in our generation has learned it. Heat it up a little and pick it out with bamboo.
Maybe there are machines now, but the principle is almost the same. Like when I make pancakes, I usually use four pancakes. Two pancakes are put on the pancakes. When it comes to that, the pancakes are made of pancakes. Haha, well, then put the dishes on the pancakes evenly, and then put the other two pancakes on it. Then, you can find a pan cover smaller than pancakes and press it on top, but not too small, so that the vegetables can be cooked quickly, and the pancakes on the upper and lower layers can be stuck together because of the pressure of the pan cover, so as to prevent the vegetables from spilling out (this is the problem with our Tengzhou dish pancakes, which are messy).
Then, heat the pancakes to two golden sides, and give them a well composition. Fold the pancakes in three equal parts, and then fold them in half along the middle.
